电动工具通用电机换向器

A collector commutator is a moving part of a rotary electrical switch in electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit. It consists of a cylinder composed of multiple metal contact segments on the rotating armature of the machine. The commutator is one component of a motor; there are also two or more stationary electrical contacts called "brushes" made of a soft conductor like carbon that press against the commutator, making sliding contact with successive segments of the commutator as it rotates.

集电极换向器应用

集电极换向器用于直流电机、发电机和通用电机。在电机中，换向器向绕组施加电流。通过每半圈反转旋转绕组中的电流方向，就会产生稳定的旋转力（扭矩）。在发电机中，换向器拾取绕组中产生的电流，每半圈反转电流方向，充当机械整流器，将来自绕组的交流电转换为外部负载电路中的单向直流电。
